Title: Improvements relating to cap devices
IPC: B65D41/00
Filed: 1944-02-11
Abstract: 571,235. Screwcap stoppers. ALLAM, P. S. (Tinnerman Products, Inc.). Feb. 11, 1944, No. 2553. [Class 125 (iii)] [Also in Groups XIV, XXII and XXV] Caps or knobs to engage with threaded or plain necks, bolts or pins are made from a single piece of sheet material with a hollow body and a number of tongues extending inwards from the open end of the body and spaced to provide an opening to receive the bolt &c. As applied to a cap for the screwed neck a, Fig. 1, of a container, a sheet metal blank 16, Fig. 4, provided with lugs 17 and notches 18 is first domed to form the body 11, the lugs being at the same or a subsequent operation bent at 13. Further operations bend the lugs inwards about their junction with the body, the notches 18 permitting them to lie in the same plane as the base of the cap, and twist the ends so that the points lie on a helix of the required pitch. The cap may be provided with four lugs. The cap may be polygonal, e.g. octagonal, for use with a spanner, and the ends of the lugs may be turned up and provided with a number of embossed threads. In making this form the body is cupped to the required form with the lugs 52, Figs. 20 and 21, extending outwards and provided with T-ends 53 in which grooves 54 are pressed. The T-ends are bent downwards and curved outwards, Fig. 23, to suit the screw and finally the whole lugs are bent inwardly about their junction with the body bringing the grooved ends into screw-engaging position. The grooving may be omitted and the threads may be cut by a tap as the final step. The lugs may be bent upwards at 72, Fig. 28, the grooved ends 73 then being bent downwards.

Title: Improvements in or relating to sheet stacking means, particularly for printing machines
IPC: B65H31/32
Filed: 1953-01-29
Abstract: 726,547. Sheet-delivery apparatus. FABER & SCHLEICHER AKT.-GES. Jan. 29, 1953 [Feb. 9, 1952], No. 2604/53. Class 100(1). Receivers.-In a device for stocking sheets, a grate having a transverse member may be removably introduced into the device between guides in the region of elements which stop and align the sheets delivered on to the grate, the stop elements upon introduction or removal of the grate being movable by the transverse member, into a position in which allows passage of the transverse member, and being automatically returned into their operative position after such passage of the transverse member. As shown, the apparatus comprises a conveyer 1 (Fig. 1) for stacking sheets on a table where they are deposited between front stops 9 and side stops 25, the latter being reciprocated by any known means. After the stack 3 of sheets has reached a predetermined height the table 2 is manually lowered far enough to enable an auxiliary table in the form of a grate 5 to be slid along supporting rails 4. The grate comprises slats 5a united by cross-pieces 7, 8. In order to avoid obstruction by the front stops 9 the latter are made in two parts 11, 12, the part 11 being turnable on a shaft 10 while the parts 12 are adapted to rock about a shaft 13 which is capable of swinging movement about a pivot 17. Thus the cross-piece 8 encounters the plate 12 on being pushed into position (Fig. 2) and causes it to rock about the shaft 13 under the action of a spring 14 which biases the parts into closed position. When the grate 5 is withdrawn the parts 12 together with shaft 13 rock about the point 17 (Fig. 3). For this purpose the shaft 13 is journalled in arms 15 pivoted at 17 to a lever 16 fast on the shaft 10. Also fixed on the shaft 10 is a lever 20 which serves to oscillate the front stops so as to align the sheets. The oscillating motion is imparted to the lever 20 by a cam mechanism 21, 22, 24.

Title: A system for the impedance measurement
IPC: H04B3/46
Filed: 1958-01-27
Abstract: 884,428. Bridge circuits; impedance measurement. DAINICHI DENSEN KABUSHIKI KAISHA. Jan. 27, 1958 [Jan. 28, 1957 (2); March 19, 1957], No. 2622/58. Class 37. In apparatus for measuring an impedance having real and imaginary parts, a bridge circuit is fed with two different frequencies, and the corresponding output currents of the bridge are separated, the one output current being used to balance one part (real or imaginary) of the impedance, and the other output current providing an indication of the other part (imaginary or real) of the impedance. As shown, a direct current source S1 and a 1000 c.p.s. alternating current source S2 are connected across diagonal CD of a bridge circuit. Two circuits under test whose unbalance due to mutual coupling is to be measured; e.g. the unbalance of two circuits in a telephone cable due to electrostatic cross-talk coupling, are respectively connected across terminal pairs A, B and C, D of the bridge; detecting subcircuits I and II also being connected across terminals A and B. Subcircuit I converts the D.C. output of the bridge into a 60 c.p.s. signal which is fed after amplification to controlling coil RC of a reversible motor M, coupled to variable resistor VR of the bridge, and excited by a 60 c.p.s. voltage fed to coil MC. Motor M will thus rotate in one direction or the other to achieve zero D.C. output from the bridge, the resulting setting of resistor VR providing an indication of the real component of electrostatic coupling between the circuits being tested. Since the alternating voltage S2 is constant, the A.C. output from the bridge is dependent upon the capacity coupling of the circuits being tested, and an indication of this coupling is provided by D.C. ammeter AM fed from bridge modulator Q which serves as a phase-sensitive detector. In another embodiment, Fig. 2 (not shown), the bridge arms comprise variometer and potentiometer windings, and the bridge is fed with two A.C. voltages of different frequencies; the bridge being balanced for both real and imaginary components of the unbalance current by two reversible motors driving respective tappings of the two potentiometers.

Title: Improvements in and relating to electron discharge switching devices
Inventor: LEVY MAURICE MOISE
IPC: H01J31/06
Filed: 1949-02-01
Abstract: 686,826. Electron discharge apparatus. GENERAL ELECTRIC CO., Ltd. Jan. 11, 1950 [Feb. 1, 1949], No. 2771/49. Class 39(i) A unidirectional magnetic field which extends at right angles to a plane cutting the cathode, surrounding anodes and apertured control electrodes produces in conjunction with the electrostatic fields an electron beam which is rotated about the cathode to pass in turn through the electrode apertures to impinge on the anodes. The rotation may be continuous or stepwise. A cathode 10, Fig. 1, may be arranged within six electrode sets each of which consists of an apertured control electrode 11, modulating grid 17, and anode 23. With a magnetic field perpendicular to the plane of paper and the control potentials shown to produce the indicated equipotential lines, a beam is focused through the control electrode 50 on to the anode 26 being modulated by the grid 20. The rotary application of the zero pulse on electrode 50 to the other control electrodes will cause beam rotation. An accelerating grid may surround the cathode. Zero voltage pulses may be applied successively to opposite control electrodes to produce two rotating beams which are diametrically opposite. In other arrangements, the anodes form a continuous ring surrounding a central cathode, modulating electrodes and radial control electrodes which are arranged between positive segmental electrodes. In another form, the modulating electrodes 68, Fig. 3, are surrounded by a screen 80, spade-shaped members 81, 94 projecting from the screen 80 and the electrodes 68 respectively; the beam split by a spade 81 is modulated by a pair of grids 106 and collected by two anodes 108. All the grids and anodes may be connected respectively to common terminals. In a further form, Fig. 4 (not shown) resistances are connected in series with positive radial control electrodes between which the anode segments are arranged asymmetrically. Beam rotation is started by a negative pulse on one control electrode; the sequential build-up of negative impulses on successive control electrodes being developed by electrons from the beam. Change of direction of beam rotation can be achieved by positional adjustment of the anodes or by the selective use of two alternative sets of anodes. In Fig. 5, anodes 164 are separated by main spadeshaped control electrodes 140, secondary spades 146 and final spades 152. Primary spades, carrying potentials the polarity of which is shown, are disposed on either side of the inner ends of the spades 140. Each spade is made negative in turn to rotate the beam. Each set of electrodes 140, 146, 152 is connected respectively to common terminals which may be fed from a single oscillator. When the device is used as a multi-channel pulse transmitter, all the anodes may be connected together. Specification 653,878 is referred to.

Abstract: 284,357. Giebe, E., and Scheibe, A. Jan. 28, 1927, [Convention date]. Piezo-electric crystal units. - Transverse or torsional oscillations are produced in a piezo-electric crystal Q by means of an irregular alternating-current field produced by a plurality of electrodes E1 - E4. By varying the cutting of the crystal and the position of the electrodes the crystal can be made to vibrate about the optical axis, any one of the electric axes or any one of the neutral axes. The crystal is mounted in a vacuum to avoid the damping effect of surrounding air and to render the vibrations visible by the luminous phenomena described in the parent Specification. The natural frequencies of the crystal, for example a rod, are modified by the addition of weights to, or by otherwise loading, the crystal, for example on the parts extending beyond the electrodes. According to modifications, the crystal is in the form of a ring (Figs. 6 and 6<a>, not shown), or of a rod thickened at the middle (Fig. 7, not shown). Specifications 239,175 and 252,170 are referred to.

Abstract: 305,216. Enschede, H. J. D. D., Enschede, J., and Enschede, B. F., (trading as Enschede en Zonen, J.). Feb. 3, 1928, [Convention date]. Offset machines; inking-apparatus.-An offset printing-machine is constructed to print from an aluminium or zinc plate, such as is used for lithographic printing, but printing is effected by etching the design in the plate to a slight depth, e.g., between 0.15 and 0.20 of a millimetre. A plate so etched is attached to a cylinder 3, and it is inked by an inking-roller 2 formed of a stiff roller provided with a thin elastic cover such asa rubber blanket. The roller 2 receives ink from supply rolls 1, and is mounted so that it is pressed against the raised parts of the design plate with a definite pressure, and it is positively driven. The offset roller 4 is also mounted so that it can be pressed against roller 3 with a pressure greater than that of the inking-roller 2, so that its elastic surface penetrates more deeply into the etched plate, and so takes up all the ink. The invention is also applicable to offset machines printing from flat plates co-operating with a flat platen on a rolling offset cylinder.

Abstract: 738,848. Electric lamps; infra-red heaters &c. DISTILLERS CO., Ltd. Jan. 22, 1954 [Feb. 4, 1953], No. 3123/53. Classes 39 (2) and 39 (3). A source of thermal and like radiation, more particularly of infra-red rays, comprises a metal chamber 1 provided with evacuating tubes 4, 5 and a front opening closed by a window 3 behind which a funnel 2 of thermally conductive material, such as copper or brass, is located with its inner end adjacent to a metal strip 7 which is supported at both ends within the chamber and connected in an electric circuit, the position of the metal strip being such that the extremity of the funnel adjacent to the strip coincides with the portion of the strip at the operating t emperature it is desired to use. The inner end of the funnel opening is preferably of square or rectangular section ; the outer end, which may be circular, is covered by a window 3 of glass, quartz, or sapphire. The metal strip 7 is carried by end members 8 and 9 supported and tensioned by springs 10, 11, the spring 10 being connected by a conducting bar 12 to a head 15 which is engaged by a terminal screw 16 extending through a solid glass bulb 17 sealed within an opening in the chamber. Rotation of the strip 7 during the adjustment of its tension is prevented by providing the bar 12 with an insulated bush 13 of rectangular cross-section which fits slidably within a constriction of corresponding section. A similar bush 19 is provided on the other end connecting bar 18 which passes through a glass bulb 21 sealed within the adjacent end of the chamber 1. The chamber, which is made of metal of high thermal conductivity and high thermal capacity, such as copper or brass, has its interior surface blackened so that it may absorb radiation of all wavelengths, whilst the funnel 2, made of the same metal, has its interior and exterior surfaces polished to reflect radiation falling thereon. The metal strip 7 may consist of any metal, e.g. nichrome or tantalum, which emanates infra-red rays when heated to an - appropriate temperature. Measurement of the temperature of the strip 7 is facilitated by a window 6 at the outer end of the tube 4 to which the evacuating tube 5 is connected.

Abstract: 588,312. Loud-speakers. HORSBURGH, G. D. L., TETLEY, F. W., and SWIFT, LEVICK, & SONS, Ltd. Feb. 8, 1945, No. 3183. [Class 40 (iv)] [Also in Group XXXV] A loud-speaker magnet having an annular airgap between a stem-like member and an apertured plate which surrounds it has its parts located by a block of non-magnetic material moulded or cast in position. In a form which is capable of being dismantled, Fig. 1, a circular magnet 18 is assembled with polepieces 10, 13, by means of an air-gap templet 14 and a non- magnetic core-ring 20 which are removed by dismantling the assembly when the mouldable material has set. The mouldable material may be a resin or other plastic applied in powder form or an anhydrous liquid such as molten sulphur, which may also be mixed with sand or a low melting alloy. Punched dimples 22a, which may be replaced by screws or pegs, locate the polepiece 10 and when the baseplate 19, which may alternatively be apertured for the insertion of the mouldable material, is replaced, cement 23 is inserted to locate the magnet assembly in the extension 24 of the speaker frame. In a modification not intended to be dismounted, Fig. 2 (not shown), the corering, which may be of brass, has an annular recess and is left screwed to the outer pole-plate. In further modifications, the speaker frame extension may be a conical continuation of the frame and may have tongues to provide keys with the cement, the plate 10 also having extensions for this purpose. In larger dual forms, the circular magnet may be assembled from arcuate segments held together by a flexible band and spaced by non-magnetic blocks which may be of wood. A dual form is also shown in Fig. 7, in which the magnets 70, 71 are within the yoke 73, 74, the assembly being retained by mouldable material 79, 82, 88, the last having a tapered bore 87.

Title: Improvements relating to blind-landing systems
IPC: G01S1/02
Filed: 1939-01-31
Abstract: 524,526. Directive wireless systems. STANDARD TELEPHONES & CABLES, Ltd., and ARMSTRONG, L. J. HEATON-. Jan. 31, 1939, No. 3309. [Class 40 (v)] In a monitoring arrangement for an overlapping beam transmitter, the outputs from two similar receivers symmetrically located on each side of the course line are combined, and any deviation from the normal operation of the transmitter is made to operate an alarm. In Fig. 2 the A.F. outputs from the two receivers A and B are opposed across the transformer TR1, and the resultant current is rectified at R to energize the relay winding 1. During normal operation of the transmitter when the resultant current is of a constant normal strength, the relay armature 3 is held midway between the contacts 2, 4 and the voltmeter shows a steady deflection. Alternatively the outputs from the two receivers may be combined in opposition and fed directly to the relay. If the transmission varies from normal so as to affect both of the overlapping characteristics, e.g., failure of the radio or modulation frequency, change in the strength of the beam, broadening or narrowing of the beam, or swinging of the beam from the correct direction, the resultant current will be greater or less than normal, and the aural or visual alarm 5 is continuously operated by the closure of contacts 4 or 2. The voltmeter V indicates the nature of the change in resultant current. If the transmission varies from normal for only a portion of the keying cycle, e.g., by failure of one of the complementary signals, or -by mistiming of the keying relays, the alarm is operated intermittently. In the former case the alarm will operate in the rhythm of the complementary signal that has failed. The alarm may be energized through a delay device so that it is not operated by objects moving temporarily across the beam.
